[0003] In this faucet fixing structure, the fixing surface is sandwiched between a fixing pedestal disposed on the front side of a mounting opening opened on the mounting surface of the faucet main body and a retainer disposed on the back side. The pedestal was fixed to the mounting surface, and the faucet body was connected to the fixed pedestal. The fixing of the fixed pedestal to the mounting surface is performed by operating a fastening means for fastening the fixed pedestal and the retainer from the surface side of the mounting surface,
The fastening means is composed of a bolt penetrating the fixing pedestal and the retainer from the front side of the mounting surface, and a nut screwed into the bolt from the back surface of the retainer. Further, a pipe hole is formed in the fixed base and a cutout is formed in the retainer, and a supply pipe for supplying hot water or water to a faucet body connected to the fixed base is passed through the pipe hole and the cutout.

However, in such a configuration, the retainer and the nut are rotatable around the bolt with respect to the fixed pedestal, and the nut rotates continuously with the rotation of the bolt. Had a configuration. Therefore, in order to fasten the fixing pedestal and the retainer with the fastening member as described above, the nut is fitted to the retainer so that the nut is integrated with the retainer, and the bolt is pulled upward to lower the retainer. After pressing the retainer against the back side of the mounting surface with the nut located at the position to prevent the retainer and the nut from rotating with respect to the fixed pedestal so that the bolt and the nut do not rotate continuously, tighten the bolt in the tightening direction. Had to be rotated.
In other words, unless the bolt is pulled up to keep the retainer and the nut from rotating with respect to the mounting base,
As a result, the fixed pedestal and the retainer could not be fastened to the mounting surface due to the continuous rotation of the bolt and the nut.

As described above, since the bolt must be tightened with the bolt pulled up, the fixing operation of the fixing base to the mounting surface becomes unstable, and the mounting operation of the faucet to the mounting surface becomes difficult. It was complicated. In addition, when the retainer is pressed against the back surface of the mounting surface by the nut, if the engagement state between the nut and the retainer is not sufficient, the bolt and the nut also rotate and the fixing pedestal is fixed to the mounting surface well. could not. Further, since the retainer is rotatable with respect to the fixed pedestal, the retainer is rotated during the fastening work, and after the fixing work of the fixed pedestal is completed, the pipe hole of the fixed pedestal and the cutout of the retainer are formed. When the position is shifted and the faucet body is attached and fixed to the fixed base,
In some cases, the supply pipe could not pass through both the pipe hole and the notch, and it was sometimes impossible to fix the faucet body.

Therefore, there is a structure in which a locking pin is provided extending downward from the fixed base and penetrating the retainer, and the rotation of the retainer is prevented by the locking pin. The mounting work on the mounting surface of the device was complicated. Further, in the configuration in which the mounting pedestal and the faucet body are formed separately, the faucet body must be connected and fixed with screws or the like after the mounting pedestal is mounted on the counter. The reliability when attached was not so high, and the appearance was not excellent. Further, the number of parts is increased and the cost is increased.
